I used Walmart tech2000 5w30 synthetic and 15-40 semi syn. I wanted to know who makes Walmart tech2000 so I called Walmart Canada. They told me to call my local Walmart, I called two Walmart Automotive Managers, one in Medicine Hat, other Swift Current.
Medicine Hat response: Tech2000 is Quaker State, Quaker State bought out by Pennzoil, Tech2000 is Pennzoil.
Swift Current response: Tech2000 was Q.S. and P.O., it is now made by Safety Kleen as of last year (Sept). The conv oils are recycled, they did not know if syn oils were. He told me Safety Kleen is a part of Esso, (I dont believe that Esso part).
I think Tech2000 may be Supertech bottled in Tech2000 lables, who knows, problem is, we dont know where this oil comes from, and if we do, wait one month and the supplier will change.
I now use only XD3, I agree with Pitzel, XD3 is the answer, name brand oil with full backing of Esso on warrantee.
One dept store carrying a great oil at great price is Super Store, look at the bottles on President Choice bottles, they are Esso bottles, the 3 stars on bottom bottle is Esso product. As an example, Esso XD3 15-40 at Esso bulk is $2.75, at SuperStore the same XD3 oil in P.C. 15-40 is $1.90 litre. I buy all synthetic XD3 at Esso bulk, cant beat price on Esso syn anywhere else, if after conv oils Superstore sells name brand oil under P.C. lable, who knows what Walmart uses for source, buyer beware.
I stopped using Walmart oil, no definite source given, I could call 100 Canadian stores and get 100 answers easy, I went through this ordeal finding out was this Tech2000 was, vicious circle, not worth it, no sleep at night not knowing what is going in an engine with this Walmart brand.
